The purpose of the study was to investigate the psychological response to the very first session of resistance exercise on positive well-being (PWB), psychological distress (PD), and perception of fatigue in untrained men and women who are obese. Forty-five (male = 22, female = 23) untrained, middle-aged volunteers (mean +/- SEM, 51.0 +/- 1.0; range, 40-69 years) participated in the study. Participants were divided into 4 groups according to sex and obesity level (i.e., men who are obese, men who are nonobese, women who are obese, women who are nonobese). The threshold for obesity was defined as waist circumference >or=94 cm for men and 80 cm for women. Measures included body composition, aerobic power, muscle strength, and quality of life (Short Form 36, SF-36). Before and after resistance exercise, participants completed the Subjective Exercise Experience Scale (SEES). Paired sample t-tests were used to assess changes in SEES scores within group pre- and post-exercise and repeated-measures analysis of variance were used to assess changes in SEES scores between groups. Exercise increased the perception of PWB in both women who are obese and nonobese, without changes in PD or fatigue. In women, the change in PWB after exercise was negatively correlated with most scales of the SF-36, particularly with the mental health dimension (r = -0.55, p < 0.01). No significant changes in PWB, PD, or fatigue were found in men who are obese. Acute resistance exercise improved PWB in women who are obese and nonobese and those with lower self-perceived quality of life scores at the start improved the most. In addition, resistance exercise did not increase feelings of distress in either women or men who are obese.
该研究的目的是调查未经训练的肥胖男性和女性在首次进行抗阻运动时，对积极幸福感（PWB）、心理困扰（PD）和疲劳感的心理反应。45名（男性22名，女性23名）未经训练的中年志愿者（平均±标准误，51.0±1.0；年龄范围40 - 69岁）参与了该研究。参与者根据性别和肥胖程度分为4组（即肥胖男性、非肥胖男性、肥胖女性、非肥胖女性）。肥胖的阈值定义为男性腰围≥94厘米，女性腰围≥80厘米。测量指标包括身体成分、有氧能力、肌肉力量和生活质量（简短健康调查问卷36项版，SF - 36）。在抗阻运动前后，参与者完成了主观运动体验量表（SEES）。采用配对样本t检验评估组内运动前后SEES得分的变化，采用重复测量方差分析评估组间SEES得分的变化。运动增加了肥胖和非肥胖女性的积极幸福感，而心理困扰和疲劳感没有变化。在女性中，运动后积极幸福感的变化与SF - 36的大多数量表呈负相关，尤其是与心理健康维度（r = -0.55，p < 0.01）。肥胖男性的积极幸福感、心理困扰或疲劳感没有显著变化。急性抗阻运动改善了肥胖和非肥胖女性的积极幸福感，且开始时自我感知生活质量得分较低的女性改善最为明显。此外，抗阻运动在肥胖女性或男性中均未增加困扰感。
